We will show that if $h$ is a Borel measurable function associated with characterizations of the uniform or Cauchy distributions, then there is no measurable solutions of the equation. Our proof uses a characterization of the Dirac measure and it is also applicable to the arctan equation.", "revisions": [ { "version": "v1", "updated": "2021-05-20T14:59:02.000Z" } ], "analyses": { "subjects": [ "39B22", "62E10" ], "keywords": [ "functional equations", "measurable solutions", "probabilistic approaches", "non-existence", "paper deals" ], "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable" } } }
